Petrochemical industries pollutants especially heavy metals affect human health and environment. In this study, impacts of poly ethylene terephthalate petrochemical industries in Mahshahr economic special zone are evaluated with Analytical Hierarchy Process (AHP) by weighting and synthesizing of health human and environmental damage criteria. In this region, main petrochemical industries are constructed close to fiords. Hence pollutants due to these industries have detrimental effects on fiords as most important ecosystem with high biodiversity. Health human damage evaluation is achieved by expressing the impacts of each pollutant on employee and local population health. Environmental damage assessment requires on intuitive expression pollutants density and environmental sensitivity. Finally nine main pollutants are evaluated according to the kind of studied petrochemical industry, TSS, Oil & Grease, COD, Heavy metals, SOX, NOX, CO2, H2S and PM. these pollutants are then compared to derive a environmental scores. Results indicate that water pollution is most important issue and TSS and Oil & Grease with 0.235, 0.326 scores from waste water discharged as highest priority should be controlled in studied area. Air pollution due to gaseous emission is second priority.
